Abstract: An orthopaedic knee prosthesis includes a tibial insert and a femoral component configured to articulate on the tibial insert. The tibial insert includes a lateral articular surface and medial articular surface that is asymmetrically shaped relative to the lateral articular surface. The medial articular surface is shaped to reduce anterior translation of a medial condyle of the femoral component, while the lateral articular surface is shaped to allow a lateral condyle of the femoral component to pivot, relative to the medial articular surface, along an arcuate articular path. Additionally, one or both condyles of the femoral component may include a femoral articular surface having a curved femoral surface section defined by a continuously decreasing radius of curvature.

Abstract: The present invention discloses a bone void filler and a method for manufacturing the same by natural calcium-containing waste, which comprises steps of mixing 5-20 wt % of a calcium-containing waste powder, 5-20 wt % of acetic acid and a remaining weight percentage of water uniformly to obtain a mixing solution; adding 5-20 vol % of a diammonium hydrogen phosphate solution to the mixing solution to obtain a suspension; controlling a pH value of the suspension to obtain an alkaline solution; leaving the alkaline solution at room temperature for precipitation for 0.1 to 72 hours, centrifuging or suction filtrating the alkaline solution to obtain a precipitate, drying and grinding the precipitate to obtain hydroxyapatite; and mixing 30-60 wt % of a pore former and 30-60 wt % of the hydroxyapatite and a remaining weight percentage of a binder uniformly to form a mixture, compression molding the mixture in a mold and sintering the compression-molded mixture.

Abstract: Polymer devices are disclosed with microstructured surfaces that modify their absorption pathway. Polymers which generally degrade in water by fracturing into high surface energy fragments, are modified to degrade in vivo without the formation of sharp fragments. Devices are disclosed that possess improved handling characteristics and degrade in an aqueous environment in a uniform and continuous way that favors the formation of soluble monomers rather than solid particulate. Absorbable medical implants with the disclosed surface modifications are more biocompatible, with reduced foreign body response, and dissolution into metabolizable molecular species.

Abstract: A heart valve prosthesis for replacing a diseased native valve in a patient, the valve includes a compressible and expandable frame structure and an anchor connected to an outer periphery of the frame structure. The anchor comprises a free end and has a flat spiral shape. The valve may further include a valve segment mounted within the frame structure and expanded with the frame structure. The frame structure may be configured for receiving a valve segment.

Abstract: A system for monitoring bone ingrowth includes an orthopaedic prosthesis having a circuit configured to transmit force sensor data indicative of an amount of force applied to a stem of the orthopaedic prosthesis in response to receiving power from an external power supply. The force sensor data is indicative of bone ingrowth of the orthopaedic prosthesis. As such, an orthopaedic surgeon may monitored the force sensor data over time to ensure bone ingrowth of the orthopaedic prosthesis has sufficiently occurred.

Abstract: A system for treating a patient comprises a delivery device and injectate. The delivery device comprises an elongate shaft with a distal portion and at least one delivery element positioned on the elongate shaft distal portion.

Abstract: Determining location and orientation of a hand-held surgical tool is provided. One embodiment captures image data that includes images of a first detectable target on the hand-held surgical tool and a second detectable target on a patient. Location and orientation or the first detectable target in a 3D space is determined based on the image data. Current location and orientation of the hand-held surgical tool in the 3D space determined based on the determined location and orientation of the first detectable target and based on retrieved model data representing the hand-held surgical tool. Location of the second detectable target in the 3D space is determined based on the image data. Then, a location of the patient's tissue in the 3D space relative to the location and orientation of the hand-held surgical tool is determined based on the determined location of the patient's second detectable target.
